LDB220 Integrated intelligent electromagnetic flowmeterDetailed product description：

The rotatable head of the LDB220 integrated intelligent electromagnetic flowmeter can rotate within a 180 degree range, making it convenient for operators to observe flow data; The product features high-definition backlit LCD display for instantaneous and cumulative flow, with an output signal of 4-20mA that can enter the DCS system PC to display flow data. Full Chinese menu operation, easy to use, simple to operate, product's online self calibration function, convenient for users to analyze instrument faults. Adopting the latest high reliability chips launched by the United States, with larger storage space; Low frequency three value rectangular wave constant current excitation is not affected by power frequency and various stray interferences on site, making the operation more stable and reliable.

The LDB220 integrated intelligent electromagnetic flowmeter adopts a new technology of non-uniform magnetic field and a special magnetic circuit structure, all of which use surface mounted electronic components. When the power is cut off, the CPU automatically saves the set parameters and accumulated values.
The range can be modified online on site according to the actual needs of the user.
